Quick Reference
The background-image property sets one or more background images (with varying placement) for an element. The default placement is at the top-left corner. As a backup, in case the image cannot be loaded, you should also set a background-color.
/* setting one background */
div {
background-image: url("my-background.jpg");
background-color: red;
}/* setting two backgrounds - the second will sit on top of the first */
div {
background-image: url("my-top-background.jpg"), url("my-bottom-background.jpg");
background-color: red;

Using JavaScript
The HTML element can also be styled using JavaScript and the element’s id.
document.getElementById('my_div').style.backgroundImage = 'url(my-background.jpg)';<button onclick='my_function()'>Click Here</button>
<script>
function my_function() {
document.getElementById('my_div').style.backgroundImage = 'url(my-background.jpg)';
}
</script>CSS Notes:
- The “inherit”, “initial” and “unset” keywords can be used with any CSS property to set its value
- In CSS there are many ways to express a color value in a property
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
